Hello,

in real project after adding control script
main()
{
while (true)
{
DebugN("bla-bla");
delay(3);
}
}

Log contains a lot of similar errors:

So, what's wrong? how to avoid it?

The log messages for the database are not related to the CTRL script mentioned in your posting.
The CTRL script only writes DebugN messages. A DebugN message does not send any information to the database.

Only with this small part of log messages we cannot see the cause for the log messages.
If you need further information please get in contact with your common WinCC OA support.
